Diagnoza Conch disc-shaped; external lobe with simple ventral secondary lobe, the dorsal secondary lobe divided into four of equal size tertiary lobes; weak secondary subdivision of the adventive lobe and multiple denticulation of the E1 lobe. Porównanie Belongs to a lineage characterized by the increasing denticulation of the sutural lobes, in which it is preceded by M. pseudodiscrepans and M. hodsoni Moore, 1958, and suceeded by M. wiswellense Moore, 1939. but details of the suture are highly variable, which makes the very existence of separate lineages of Metadimorphoceras questionable.
